Can someone do me and likely other Dolphin users a favor and provide a custom build based on master except without the PPC_FP merge that messed up Sonic Colors and other games? Thank you very much, it would be greatly appreciated until developers can fix the issues the PPC_FP merge caused. I do understand that I may forfeit support by using a custom build.

The latest development builds are bleeding edge software for a reason too. They're still WIP builds no matter how stable some of them are or aren't. I see nothing wrong with the merge; Dolphin's not going to get better if developers didn't try to make changes like this in the long run. The dev builds are going to get stable sooner or later though, I'd just sit tight or use a build before the merge.
